Trackback

A "Trackback" feature of a weblog is
useful to know which article refer to own article.
We can take advantage of this feature into indexcard. And this is
quite easy. I introduced how to link between cards. Just reverse of
the link. I use a red pen for emphasis. If there is many trackbacks
on a card, it indicates the card is useful.
This idea is originally from
a comment by riclav at flickr.
